AAn 8-inch pitch diameter steel gear, 3 inches thick (face width), is pressed onto a 2 inch diameter steel shaft(E=30,000,000 psi and v =.3). The coefficient of friction of steel on steel is.12. For press fit calculations the effective outside diameter of a gear is its pitch diameter. The gear is to transmit 90 HP at 300 RPM. What does the inside diameter of the gear need to be if the entire torque is to be carried by the press fit?
